A tragic teenager with a "beautiful soul" who died on holiday in a hotel bathroom had an undiagnosed "ticking time bomb" heart condition, his family have said.
Daniel Smyth's post-mortem found the 19-year-old man had cardiac arrhythmia, an irregular heartbeat.
But the Coleraine student was unaware he had the condition and, during a family holiday in Sunny Beach, Bulgaria last week, the student collapsed in his hotel bathroom, and died instantly.
